Abstract

The invention aims to provide an explosive shock-resistant optical fiber connector plug. The problem that the current optical fiber connector for an igniter is easy to damage is solved. The explosive shock-resistant optical fiber connector plug comprises a plug shell and a pin component arranged in the plug shell, wherein the pin component comprises a ceramic pin and a tail handle arranged at the rear end of the ceramic pin; at least one sealing ring inserted into the shell of an adaptive socket and matched with the shell of the adaptive socket in a sealing way is arranged on the tail handle of the pin component. After the plug is plugged into the adaptive socket, good sealing can be formed between the tail handle and the shell of the adaptive socket through the sealing ring, so that the phenomenon that the optical fiber connector is damaged when impact air pressure instantaneously generated by ignition explosion leaks at the place where the plug and the socket are matched can be prevented, and the problem that the current optical fiber connector for the igniter is easy to damage is solved.

Description

The optical fiber connector plug of explosion-proof impact
Technical field
The present invention relates to joints of optical fibre field, has especially related to a kind of joints of optical fibre of explosion-proof impact and has inserted Head.
Background technology
Light energy transmission is obtained for increasingly widely to apply with its advantage such as quick, accurate in all trades and professions.Example Such as in some special dimensions, in the operation such as igniting blasting optical transport technology is just used.In prior art, for igniter The joints of optical fibre be mostly that the major function of realization is the biography of system light energy using conventional ST type fiber optic connector assemblies It is defeated, although can to realize lighting a fire, but such fibre-optic connector structure low intensity, especially do not possess sealing property, in system After realizing detonation ignition function, plug with the contact of socket contact of the gases at high pressure produced by lighting a fire from connector assembly Release at face, powerful impulsive force can cause connector assembly bindiny mechanism to damage, the plug and socket of connector assembly is separated Deng failure phenomenon.Therefore, the current optical connector for igniter there are problems that flimsy.
The content of the invention
It is an object of the invention to provide a kind of optical fiber connector plug of explosion-proof impact, to solve to be currently used for igniting The flimsy problem of optical connector of device.
In order to solve the above problems, the optical fiber connector plug of the explosion-proof impact of the present invention is employed the following technical solutions: The optical fiber connector plug of explosion-proof impact, including plug casing and the contact pin components being assemblied in plug casing, contact pin components Including ceramic contact pin and the caudal peduncle for being assemblied in ceramic contact pin rear end, the caudal peduncle of the contact pin components is provided with least one for inserting The sealing ring for entering into the housing of adapter socket and coordinating with the housing seal of adapter socket.
Coupling nut is equipped with the plug casing, elastomeric element, bullet are top-loaded between coupling nut and plug casing Property part pushes backwards against coupling nut.
Pad is equipped with the housing, back-up ring is equipped with coupling nut, elastomeric element with pad and back-up ring by matching somebody with somebody Close and push up and be mounted between plug casing and coupling nut.
The coupling nut is provided with for coordinating the card for constituting bail retaining mechanism with the bail on adapter socket housing Nail.
The elastomeric element is ripple spring.
Because the caudal peduncle of the contact pin components of the optical fiber connector plug of the explosion-proof impact of the present invention is provided with least one The sealing ring coordinated in for being inserted into the housing of adapter socket and with the housing seal of adapter socket, therefore, inserting with being adapted to After seat grafting, caudal peduncle can constitute good sealing by sealing ring and the housing of adapter socket between, so as to can anti-stop The impact air pressure that fiery instant of detonation is produced leaks and damages optical connector at the cooperation by plug and socket, solves existing use In the flimsy problem of the optical connector of igniter.

Specific embodiment
The embodiment of the optical fiber connector plug of explosion-proof impact, as Figure 1-3, the optical fiber connection of the explosion-proof impact Device plug includes plug casing 11 and the contact pin components being assemblied in plug casing 11.
Plug casing 11 is metal shell substantially cylindrical in shape, and it includes the path section at the big footpath section of front portion and rear portion, greatly Footpath section is additionally provided with the gear edge protruded to the periphery to week, in addition, in the present embodiment, plug casing with the adjacent position of path section The guide groove that 11 big footpath section front portion is additionally provided with front opening, extends in front and back, the front opening of guide groove forms the splay enlarging of class Structure.
Coupling nut 12 is equipped with plug casing 11, there is the rearward step surface in face in the endoporus of coupling nut 12, its By the spacing cooperation of leading flank on the gear edge on the step surface and plug casing 11, so as to not fall out plug casing 11, plug Elastomeric element is also top-loaded between housing 11 and coupling nut 12, elastomeric element pushes backwards against coupling nut 12, in the present embodiment In, elastomeric element specifically uses ripple spring 13, is wherein equipped with back-up ring 14, plug casing in the endoporus of coupling nut 12 Be provided with pad 15 at the trailing flank on gear edge on 11, elastomeric element be pushed up by coordinating with pad 15 and back-up ring 14 be mounted in it is slotting Between casing 11 and coupling nut 12.Bail hole 16 is provided with the front end of coupling nut 12, bail hole 16 is used to be inserted with being adapted to Bail 18 on the Socket casing 17 of seat coordinates composition bail retaining mechanism, in the present embodiment, the bail on coupling nut 12 Hole 16 has four, for four bail holes 16 are compared to the three bail holes commonly connected on cap, is better able to ensure plug and fit Reliability with socket locking.
Contact pin components include ceramic contact pin 19 and are assemblied in the caudal peduncle 20 of the rear end of ceramic contact pin 19, caudal peduncle 20 in a tubular form, In the present embodiment, caudal peduncle 20 is metal caudal peduncle, and its outer peripheral face is provided with three seal grooves, and three seal grooves are along caudal peduncle 20 Axially spaced-apart arranges that sealing ring 21 is respectively equipped with each seal groove, and sealing ring 21 can be plugged together in the plug and adapter socket Coordinate with the appropriate section sealing of the housing of adapter socket afterwards.
Shown in Fig. 4 is the structural representation of the adapter socket that can be used cooperatively with the plug, it can be seen that its The front end of Socket casing 17 is provided with a seal section, when in use, the sealing after ceramic contact pin grafting in place, on caudal peduncle 20 The inwall face seal of the seal section on the Socket casing 17 of circle and adapter socket coordinates, so as to just prevent the gas of igniting explosion time Pressure leakage, prevents optical connector to be damaged.
